全民健身大潮中，有两个词，你一定不陌生——有氧运动和无氧运动。

有些人仅从字面理解，认为无氧运动就是耗氧量比较少的运动，还有些人认为，无氧运动就是不怎么出汗的运动，相对应的有氧运动则是会让人大汗淋漓；而还有一部分人认为，有氧运动负责减脂，无氧运动负责增肌……

那么这两种运动模式，究竟是如何定义？它们之间又存在着怎样的关系？

其实，这两种运动模式的

区别在于，提供能量的代谢方式不同

。有氧运动主要通过有氧代谢来提供运动时候需要的能量，相对应的，无氧运动自然指的就是，通过无氧代谢来提供能量的运动方式。

听起来似乎是界限分明，但实际上，

有氧供能和无氧供能方式很少独立存在，往往都是多种供能方式同时作用。

因此，所谓的有氧或者无氧运动，也只是按照主要供能方式的不同来进行区分。

随着生活节奏加快、工作压力增大，很多人为了保持健康和身材，将“减脂减重”作为自己生活中的一项任务。其中，

无氧运动跟有氧运动一样，都有很好的减脂效果。

脂肪是我们身体里的能量储备，只要消耗能量，自然就消耗脂肪。只是，有氧运动和无氧运动消耗能量的时间段不同。有氧运动主要在运动过程中消耗能量，而无氧运动在运动结束之后还会持续消耗能量，并且

降低能量转换成脂肪的可能性。

除了消耗能量、减少脂肪存量之外，无氧运动还具有塑形的好处。

很多人害怕无氧运动把自己练成大粗腿、金刚肩，这不仅是一种“多虑”，而且还让你减脂工程的效率大打折扣了！无氧运动虽然有增肌的效果，但想练出很大的块头，绝不是业余时间随便举举铁就能做到的。而且，

随着肌肉含量的提高，自身的基础代谢也会随之上升

，身体消耗的能量更多，反而更有利于我们减脂。
